Solar Monitor Plug Polarity Test
1. Release water from the T&PR valve until the water temp in the cylinder is < 75ºC.
2. Switch off power for 5 seconds and then restore power.
3. If the LED flashes green (any combination) or is solid red within the first 15 seconds
from restoring power, the solar monitor plug is inserted the wrong way around.
Solar Monitor LED Indication
Each flash lasts for 0.5 seconds and each series of flashes is separated by a two second
interval.
Green LED - Operational Status Red LED - Fault Condition
Flash Sequence Indicates Flash Sequence Indicates
Solid green (on) Standby mode 1 Flash Hot sensor open circuit
2 Flash Flooding solar circuit period 2 Flash Hot sensor short circuit
3 Flash Pump(s) flow control period 3 Flash Cold sensor open / short circuit
4 Flash *Pump flow established. 4 Flash
Open or short circuit of any top
3 thermistor on sensor strip
5 Flash Cylinder at maximum temp. 5 Flash Sensor strip unplugged
* When pump flow is established auxiliary pump 2 is turned off by the control board (if
fitted) whilst pump 1 continues to operate.
Components and Their Function
Temperature and Pressure Relief Valve (T&PR)
A valve designed to provide automatic relief by discharging water in case of excessive
temperature and/or pressure.
Never fit a T&PR Valve with a pressure rating greater than that indicated on
the product-rating label.
Storage Cylinder
A fully welded steel cylinder incorporating a convex (plus) top, concave (minus) bottom
and central tube (heat exchanger). The cylinder is lined with vitreous enamel to provide
protection against corrosion throughout the life of the water heater.
Outlet Delivery Tube (Dip Tube)
A plastic tube installed in the hot water outlet of the water heater cylinder to conduct water
from the highest point to the outlet connection. It also acts as a fitting liner.
Fitting Liner
A plastic tube installed in the cold-water inlet of the water heater to provide protection
against corrosion throughout the life of the water heater.
Cold Pipe (Solar Return)
The pipe connecting the solar collectors to the storage water heater through which the
cooler solar transfer fluid returns from the storage cylinder to the collectors.
Hot Pipe (Solar Flow)
The pipe connecting the solar collectors to the storage cylinder through which the solar
heated solar transfer fluid flows back to the storage cylinder from the collectors.
Electronic Controller
An electronic control unit that interprets low voltage signals indicating water temperature
from the hot and cold sensors to switch on and off the 240 volt circulating pump circuit.
The unit is factory set and cannot be adjusted or mega-ohm tested. Refer to page 15 for
more information.
